The Halcyon Evolve donut wing provides incredible control, allowing you to fine tune their buoyancy regardless of the position you're diving in.

The ease of adjustment and the streamlined design of the wing (hugging your cylinders) makes it easy to twin up two small tanks or two large heavier tanks!

Whether you're swimming or diving with a scooter, the Evolve twin wing cuts through the water beautifully and creates less drag and greater efficiency with less effort required.
